Jones of SSK Industries, the .950 JDJ was designed purely for shock value and novelty, rather than practical application. Owning one requires destructive device registration in the United States, highlighting its immense power. The recoil is so intense that it is generally advised to shoot it only from a supported position. While the .950 JDJ holds the title of largest bore diameter for some, its practicality is extremely limited.
.700 Nitro Express
The .700 Nitro Express is a more practical, albeit still extremely powerful, cartridge. Developed by Holland & Holland in the late 19th century, it was designed for hunting extremely dangerous game, such as elephants and rhinoceroses, in Africa. Firing a .700-inch diameter bullet weighing 1,000 grains, the .700 Nitro Express delivers tremendous stopping power. Recoil is substantial, requiring experienced shooters and rifles weighing upwards of 15 pounds. While not the absolute largest rifle caliber in terms of bore diameter, its widespread use and proven effectiveness in dangerous game hunting make it a significant contender.
.600 Nitro Express
Another notable Nitro Express cartridge is the .600 Nitro Express. Also designed for dangerous game hunting, it fires a .620-inch diameter bullet weighing 900 grains. Similar to the .700 Nitro Express, it delivers immense stopping power and requires a robust rifle and experienced shooter. The .600 Nitro Express offers a slightly flatter trajectory and less recoil than the .700 Nitro Express, making it a popular choice for professional hunters and guides. While smaller in diameter than the .950 JDJ and .700 Nitro Express, its balance of power and shootability makes it a relevant comparison when discussing the largest rifle caliber options.
.50 BMG (Browning Machine Gun)
The .50 BMG (12.7x99mm) is a cartridge developed in the early 20th century for the Browning Machine Gun. While not specifically designed as a hunting cartridge, it has found applications in long-range shooting and, in some regions, hunting large game. Firing a .50-inch diameter bullet weighing between 650 and 800 grains, the .50 BMG offers significant range and penetration. Its military origins mean that it is widely available and relatively affordable compared to the exotic Nitro Express cartridges. While not the largest rifle caliber in terms of bore diameter, its power and widespread availability make it a significant cartridge to consider.
Factors to Consider: Bore Diameter vs. Cartridge Performance
As we’ve seen, defining the largest rifle caliber isn’t as simple as comparing bore diameters. Cartridge performance, including bullet weight, velocity, and energy, plays a crucial role. A cartridge with a smaller bore diameter but a higher velocity and heavier bullet can deliver more energy to the target than a larger caliber with a lighter bullet and lower velocity.
Furthermore, the intended purpose of the cartridge is a critical factor. Cartridges like the .700 Nitro Express are designed for stopping extremely dangerous game at close ranges, while the .50 BMG is designed for long-range engagements. Therefore, the ‘best’ or ‘largest rifle caliber‘ depends on the specific application.
The Role of Rifle Design and Construction
The rifle itself is just as important as the cartridge. Large-bore rifles require robust construction to withstand the immense pressures generated during firing. Rifles chambered for cartridges like the .700 Nitro Express often weigh upwards of 15 pounds and feature reinforced actions and barrels. The design of the stock is also crucial for managing recoil. Stocks are often heavily padded and designed to distribute recoil evenly across the shooter’s shoulder.
The development and production of these rifles require specialized engineering and manufacturing processes. The steel used in the barrels and actions must be of the highest quality to ensure safety and reliability.
